State Submittal:
SIP revisions dated November 27, 1998, April 15, 1999 and April 18, 2000.

Affected Areas:
New York portion of the New York, Northern New Jersey, Long Island severe
ozone nonattainment area.

Summary:
New York submitted a 1-hour ozone attainment demonstration. This demonstration
consisted of: photochemical grid modeling results for three episodes representing
different weather conditions, additional evidence to demonstrate attainment
for the nonattainment area, VOC and NOx emission inventories, and identification
of control measures needed to attain. EPA evaluated this information and
performed additional analysis and concluded that additional assurances
were needed to conclusively determine that the New York 1-hour Ozone Attainment
SIP will result in attainment. New York provided this assurance by committing
to adopt additional control measures which would result in the EPA-identified
VOC and NOx emission reductions and to perform a mid-course review which
would determine whether New York was still on track to attain.

New or Revised Regulations Included As Part of the SIP:
None

Commitments:
The SIP revisions include the enforceable commitments for future actions
associated with attainment of the 1-hour ozone national ambient air quality:

To adopt additional control measures by October 31, 2001 to meet
the level of reductions identified by EPA for attainment of the 1-hour
ozone standard;
